False error: Please choose product options… After WP 4.5 actualization

Without a link, no one can check.

We are having the same issue – on this website, JN Equipment – we updated WordPress to 2.5 (more like GoDaddy did that automatically…)

And the Variation items are broken. Interesting enough on one of our websites where GoDaddy did not automatically update up to 2.5 for WordPress, Variation items still work fine:

Even more interesting than just plain out not working right is also the fact that you cannot even clear the selection on the JN Equipment website. It’s like it does not even ever access the variation data at all.

Both sites run with pretty much the same plugins and Woocommerce 2.5.5.

Furthermore, the sites with update to 2.5 of WordPress also broke all the variation images.

Immediate help & notice/warning to not update to 2.5 of WordPress should be posted.

Okay we have resolved the issue. The problem was with the theme ‘Divi’ from Elegant Themes. I would like to refer at this point where we found the solution:

Divi
Divi Version 2.7.3 ( updated 04-13-2016 ) fixes the jQuery issue outlined below. Update your theme.

It appears many other themes have conflicts with WP 4.5 according to the post linked above. So make sure everything is up-to-date!
